I went to a hugging workshop at Bromyard Folk Festival a few years ago, it was great fun! It certainly broke the ice and allowed us to laugh at our slef consciousness. I suppose I do hug quite a lot, but I am also very aware of my own personal space, that is one thing that bugs me, when people invade MY personal space, standing too close, touching un-necessarily etc. A good honest hug I can cope with but not someone in my face!
